■ Working Conditions
1 suction pressure ≤ 1.0Mpa, hydrostatic test pump pressure is 2.5Mpa, please specify when ordering system working pressure . Pump system working pressure greater than 1.6Mpa should be made when ordering.
2 the transmission medium volume solids content per unit volume of not more than 0.1% , a size of ≤ 0.2mm.
■ The main purpose
SPL (W) water-cooled feed pump for conveying water and physical and chemical properties similar to other liquid water , applied to urban and industrial water supply and drainage , high-rise building pressurized water, garden irrigation, HVAC refrigeration cycle and other places. For pumping water at room temperature .
■ Features
Low noise: Since the motor and pump portions of the pump in the pipe is completely closed , the pump motor is partially surrounded by a liquid transport relying on the flow of water for cooling the cooling motor (conventional centrifugal pump to the motor by the motor cooling fan ) , the noise can be reduced to 40 decibels ( general equipment 80 - 100 decibels) .
Small footprint, easy installation: water-cooled feed pump installation is very flexible, convenient , no need to build pumping stations, small space requirements , can work in a wet environment . This type of pump can be vertical, horizontal mounting , can be directly connected to the existing pipeline through the pipe section or flange , and can be connected to a bypass pipe .
Energy-saving , reliable: the unit adopts frequency control, soft start, soft stop, start current, so that the operating conditions of the pump and pipe network characteristics best fit , the unit energy efficient . Along with the lack of protection, overload , overheating and water and other protection, and ensure long-term reliable operation of the unit .
